The focus is real-time spatial/bodily interaction between distant participants via real-time 3D image (and sound) traces. In "Traces", each CAVE will use multi-camera machine vision to build real-time body models of participants. These body-models will then be used to generate abstracted graphical bodily traces in the other CAVEs where a person may be represented as a moving ghostlike transparent and wispy trace.

My goal is to build a system with which the user can communicate kinesthetically, where the system come closer to the native sensibilities of the human, rather than the human being required to adopt a system of abstracted and conventionalised signals (buttons, mouse clicks, command line interface...) in order to input data to the system.
